Unquestionably one of the biggest rock bands of the 1990s, Pearl Jam, in many ways, were the star students of the grunge class. Though they didn't have the defiant, punk attitude of Nirvana nor the we-love-Sabbath metal edge of Soundgarden, the quintet found a huge audience for their relatively straightforward rock, thanks, in large part, to frontman Eddie Vedder's intense persona and distinctive vocals. As the band grew to resent their success, their music became intentionally less accessible (and often more intriguing), and while their peers folded, Pearl Jam found themselves with a smaller, but still loyal, fanbase by the first years of the 21st century.
